Costco Pharmacy Reviews

I have been having issues with the mail order pharmacy since my first fill with them. I don’t know how you can bill someone 499 and the patient is the one who has to find your mistakes multiple times. When you are only supposed to be charged 24.99. That’s an huge difference And every month they mess it up and no one will work hard enough to figure out what the issue is. They don’t care at all about their customers. It is so stressful. I think they need people who know how to do the job and care about getting the right answers instead of screwing you without any care in helping you.

I’m sorry you had to deal with all of that — especially for a medication you depend on. Here’s a polished version that keeps the frustration clear while still sounding professional and credible: I am extremely disappointed with the level of service I received from Costco Pharmacy. Last week, I called to refill an important prescription and was told they only had a 3-day supply available immediately, or I could wait until Friday for the full refill. I explained that I would be working 12-hour shifts and would not be able to pick it up Friday or Saturday. I was then advised that I could pick it up Sunday from a locker.

I had a prescription for a pet filled previously at a Costco location with no issues so because we were in the optical department at the store anyway I dropped off a script for my canine thinking it'd be easy peasy. Ha! Worst pharmacy experience EVER. Completely unorganized and incompetent; they could only fill a partial and were supposed to complete the fill within 3 days, 4 days later I called and left a message inquiring as to status, next day I get a voicemail a little after 9AM saying it would be filled that day - mind you, I'm driving over 30 minutes to get to this Costco and at 4:30 PM headed back that way as we had another appointment close by at 5:30 - still no refill.

After filling the same medication multiple times at Costco, the pharmacist refused to fill the med that was due yesterday, reason being because I had seen a "new provider".. Tried to explain that provider is within the same practice/medical office. Then pharmacist said she wouldn't fill it because the office is too far. What?! I explained it's a televideo visit and in the same state of Texas. Nope. Still no fill. Had to call my doctor this am to "reassure" this ** pharmacist who is either in a power trip or just insecure and incompetent. She said she would fill it "tomorrow". Had husband make a fourth call to say I cannot wait any longer. She agreed fill it today. 🙄

Since 1/1/2026, when my new pharmacy insurance went into effect, I have submitted two prescription refill requests. Both times, I have received notifications that my prescriptions are ready for pick up. The first prescription I waited for over an hour because the computers were down. Trying to pick up the second prescription was the same reason; the computers were down. I left without my prescription.

If I could give a zero I would. The staff tries to help at times but they have no clue about their app nor being able to help solve the issue after multiple in person visits. I do not get text messages as I should. Worse, my son’s diabetes meds are not being filled for one reason or another. Now an update was sent by his dr and Costco shows it was cancelled, so once again they cannot help. 2 weeks prior I couldn’t fill a 90 day prescription for insulin because I had to wait 109 days. What the heck. Now we have no insulin and no Dexcom when it all came via mail prior to 7/2025 with no issues every 90 days under another servicer.

To be treated like I'm a drug addict for trying to get my medication 2 days early because I'm going out of town is crazy. My doctor wrote a note stating I can pick up early and the pharmacist take it into their own hands like they are d.e.a. agents breaking a drug lord's ring of illicit drug manafacturing ring is crazy. As the pharmacist quote "You shouldn't be out since you pick up a day before for your refill, is due for the past 8 months." Is crazy, shouldn't they just fill the perscription read what the doctor. Says and shut up? I will definitely not be going to this pharmacy again which sucks because they are so close to the house.

Costco is absolutely the worst mail order pharmacy I have ever dealt with. Nothing makes sense when you look at your prescriptions. Some of them don't show up on the web page. Some of them you can't get 90 day supplies far. I've got two different medications which are generic. One of them cost $1.73 in the other one $103. It's absolutely horrible.

Take a heart medication ticagrelor 80mg and 180tabs. On Good RX can get a coupon cost of $62 at Target (CVS). At Costco pharmacy the cost with Good RX coupon is $1126. Check yourself. This is insane overcharge for exact item.

Biggest idiots ever!!!! Constant issues every single time you deal with them. The call center you end up talking to is a complete joke, not to mention you can't understand half of them. I have never in my life seen more incompetent people in any company.
